Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight to measure because it affects the total
or gross weight of your vehicle. The Gross Vehicle
Weight (GVW) includes the curb weight of the
vehicle, any cargo you may carry in it, and
the people who will be riding in the vehicle. If you
have a lot of options, equipment, passengers
or cargo in your vehicle, it will reduce the tongue
weight your vehicle can carry, which will also
reduce the trailer weight your vehicle can tow.
And if you will tow a trailer, you must add the
tongue load to the GVW because your vehicle will
be carrying that weight, too. See Loading Your
Vehicle for more information about your vehicle’s
maximum load capacity.
The trailer tongue weight (A) should be 10 percent
to 15 percent of the total loaded trailer weight (B),
up to a maximum of 400 lbs (181 kg) with a
weight carrying hitch. The trailer tongue weight (A)
should be 10 percent to 15 percent of the total
loaded trailer weight (A), up to a maximum
of 900 lbs (408 kg) for a weight distributing hitch.
